The FBI's Washington field office said the school's associate director of the Center for Health Policy, Frank Lombard, was caught in an Internet sting.

Authorities said that Lombard tried to persuade a person -- whom he did not know was a police officer  to travel to North Carolina to have sex with Lombard's child. Court documents say Lombard told the officer that (Lombard) had performed multiple sexual acts on the child.

Court documents also say that Lombard identified himself online as "perv dad for fun" and "perv fam fun," a reference to incestuous child molestation. According to the arrest warrant, the informant said he was chatting with Lombard using a program called ICUii, which allows users to chat online while viewing live video images of the other user.

The informant said Lombard identified himself as cooper2 or cooperse," lived in the Raleigh/Durham area, and had another adopted child and a live-in gay partner who did not participate in the child's abuse. A subpoena of the ICUii account connected Lombard to the usernames, the warrant says.

The papers also say an unnamed informant, facing charges in his own child sex case, tipped off authorities to Lombard's alleged activities. The informant indicated he was told that others had sexually molested the child, the documents say.

He was arrested at his Durham home on Wednesday. Two children at the home, including the 5-year-old child allegedly offered for sex, were taken into protective custody by the North Carolina Department of Social Services.
